Product Description

The smallest BBSHD ring that keeps a proper chain line

Normally, going smaller than 42T on a BBSHD means giving up chain line, because small rings have little offset. Lekkie solved that with this package. A slimmer replacement drive cover frees up room on the side of the motor, which lets a 40T ring sit with plenty of offset. You get lower climbing gearing and a chain line that shifts cleanly.

The 40T also has an external chain guide ring. It adds chain retention and keeps your pant leg away from the chain.

What's in the box

  • 40T Bling Ring (CNC 7075 T6 aluminum)
  • Lekkie Drive Cover for BBSHD
  • MULTISPACER

Important: a 40T ring can only run with the Lekkie drive cover. That's why it's sold as a package. Don't install the ring on a stock cover.

The MULTISPACER: 5mm of adjustment in one part

  • Keyed into the back of the ring: standard Bling Ring offset.
  • Removed: 2.5mm extra offset, pulling the chain line in toward the frame.
  • Flipped: spaces the ring 2.5mm outward for extra frame clearance.
